Synovium tissue in the spine provides fluid to help lubricate the facet joints in the lumbar, or lower, spine.
When degeneration of these joints occurs, usually as part of the natural aging process, fluid can build up to protect the joint and in turn create sac-like protrusions called synovial cysts. The cysts can place pressure on the nerves inside the spinal canal as well as narrow the canal, potentially causing pain and discomfort.
Spinal synovial cysts are benign and are most common in individuals 65 and older. Symptoms can remain stable long-term, and if deemed manageable, may not require any medical intervention.
